Application filed August 12, 1904. Serial No. 220,453.

To wZZ whom it may concern:

Be'it known that I, JOHN J. HENNESSEY, a citizen of the United'States, residing in Mil- Waukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Rail way-Car Frames and B01- sters, of which thefollowing is a specification;

My invention relates to improvements in the frame or sill and bolster construction of railway-cars.

The object of myinvention is to provide car-frame sills and bolsters of a simple, strong, efficient, and durable construction in which the center sills, and body-bolsters will both be continuous and of full strength and properly anchored each in respect to the other and at the same time each be at the proper height or level in respect to the floor-frame and in which both the center sills and the body-bolster may be of simple form, capable of being cheaply manufactured and readily put together in constructing the car, and also to materially diminish the overhang of the center sills and their consequent liability to yield or gilil e downward at the middle and ends of the s1 s.

My invention consists in the means I employ to practically accomplish this object or result-that is to say, it consists, in connection with the side and intermediate sills and center sills of the car-floor frame, each of which may be of any suitable materialyas wood or steel, and if of steel of any suitable form in cross-section-such as Z-beams, channel-beams, I-beams, or other suitable shape, but preferably Z-beams-of a body-bolster preferably of cast metal furnished with transverse slots or'notches or recesses to receive the center sills preferably to about half the depth of the center sills and provided at its middle portion in its upper face with a longitudinal channel or recess to receive a fiat stopplate or key-plate which extends through central slots in the upright webs of the center sills and a bolster-reinforcing plate or strap, preferably of cast metal, extending over the center sills and having arecess or chamber to receive the center sills and securely riveted or bolted at its ends on each side of the center sills to the body-bolster. The short key or stop plate, which extends through the slots of the center sills, fits and is clamped between the body-bolster and the bolster-strap or reinforcing-piece, and the center sills are thus securely anchored to the body-bolster by the key or stop plate, and the pulling and bufiing strains of the draft-rigging on the center sills are thus communicated to and resisted by the body-bolster and the whole car-frame, which is connected thereto, and while the center sills,

in a sense, pass through the body-bolster or through the opening between the recessed body-bolster and the recessed bolster-strap or reinforcing-piece the bolster by reason of the reinforcing piece or strap is, in fact, given as a whole a much deeper and more effective cross-section at its middle or recessed portion, and consequently much greater strength at its middle portion, than at other portions of its length, as the bolster-strap or reinforcing-piece, securely riveted or bolted at its ends to thebolster, may be considered as an upper bolster member'or integral With the bolster, so far as imparting strength thereto is concerned.

My invention also consists in the novel con struction of parts and devices and in the novel combinations of parts and devices herein shown or described.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of a device embodying my invention, showing, however, only the portion of. the carsills adjacent to the body-bolster. Fig. 2 is a cross-section on line 2 2 of Fig. 1. Fig. 3 is a vertical section longitudinal of the bolster on line 3 3 of'Fig. 1. Fig. llis avertical section online 4 4 of Fig. 1. Fig. 5 is a cross-section on line 5 5 ofFig. 1. Fig. 6 is a detail perspective view of the stop-plate or keyplate. Fig. 7 is adetail perspective view showing the stops or shoulders on the center sill. Fig. 8 is a detail bottom view showing one end or half of the bolster-reinforcing piece or strip, and Fig. 9 is a detail top view showing onehalf of the central portion of .thebolster.

In the drawings, A represents the side sills, B the center sills, and C the intermediate sills, and D the body-bolster. The sills A, B, and C may be of any suitable material. In the drawings I have indicated them as being of steel and of a Z shape in cross-sectionthat is to say, each having an upright web f and oppositely-turned horizontal flanges f f though instead of using Z-bearns, channel-beams, I- beams, or other suitable shapes may be used, as desired. I prefer to make the sills of a Z- beam form, as I am thus enabled to use eooperating Wood or floor-nailing strips or members E, which rest at their lower edges on the lower fiangef of the sills, which thus coact or'cooperate with the sills to give great strength and stiifness thereto. The floor-nailing strips or members E project sufiiciently above the upper fiangesf of the sills to allow for shrinkage of the Wood, and thus prevent the sills interfering with the floor E, nailed to the floor strips or members E.

The body-bolster D is preferably of cast metal or steel and is provided at its ends with notches or recesses (Z to form seats for the side sills A, which are preferably made deeper than the other sills. The body-bolster D is also provided with transverse slots, notches, or recesses cl (1 at its middle portion in its upper face, member, or plate (Z preferably to a depth somewhat less than half the vertical height or depth of the center sills B to receive the center sills. The width of these notches or recesses corresponds to the width of the foot or lower flange f of the center sills, so that the walls of these recesses serve to space the center sills or hold them in place laterally. The bod y-bolster D is also provided at its upper facew-ith a wide channel or recess (Z to receive a short flat key-plate or stop-plate F, which extends through central slots bbin the upright Webs ff of the center sills B. This short fiat strap-plate or key-plate is held in place against the thrust of the center sills by the shoulders or walls CZ" of the recess or channel (Z in the bolster, and this stop or key plate is held in place longitudinally of the bolster by the shoulders or walls (Z of the sill notches or recesses (Z in the bolster. The strap or key plate while a loose flat plate is thus securely held in place in every direction on the bolster.

G is the bolster-strap or reinforcing-piece, the same having a central recess or chamber g to receive the upper portion of the center sills, over which sills the middle portion of this bolster-strap or reinforcing piece extends.

The bolster D and its reinforcing-piece or strap Gr are firmly and rigidly secured together by bolts or rivets g, which extend through the upper plate or member (Z of the bolster. The bolster-reinforcing piece or strap and bolster are further locked or secured together by interengaging shoulders cl and g on the bolster and reinforcing piece, respectively.

To diminish the overhang of the center sills and also to further strengthen the bolster at the sillnotches or recesses a5 d therein, 1 provide the bolster withintegralside wings (Z (7, one on each side thereof, having grooves or channels d to receive the sills and u 'iright flanges (Z These side wings materially extend the bearing of the center sills on the bolster, and thus diminish the overhang. The bolster, reinforcing piece or strap G is also provided with grooves or channels to receive the upper flanges or edges of the center sills and with integral lugs 0", which abut against the center sills. The center sills are also furnished with stop shoulders or brackets 6', se curely riveted thereto and abutting against the bolster at the front and rear sides thereof to increase the bearing of the center sills against the bolster and aid in resisting the longitudinal pulling or bufiing thrusts on the center sills imparted thereto from the draftrigging. The bolster-reinforcing piece or strap (Jr has a central hole for the king-bolt corresponding with the king-bolt holef" in the stop or key plate F and the king-bolt hole (Z in theintegral center-piece portion d" of the bolster D. The bolster D is also provided at intervals with shoulders (K to lit against the vertical faces of the sills. The sill-shoulders (Z are preferably integral with the bolster, and the sills are secured thereto by bolts or rivets (I The wood nailing-strips E are secured to the sills by bolts or rivets (a.
